As I am dork and just realised that not everyone will know just what the hell versions these are, they are from left to right:
Original publication of the Leroux (Castaigne); Lon Chaney/ Mary Philbin 1925; Claude Rains/Susanna Foster 1943; AlW stage artwork by Brad Parrish; an illustration from the inside jacket of the Kay novel; and the ALW stage version Red Death.
